304SS 2.5" 0-3,000 PSI/ 0-210 Bar Liquid Filled Pressure Gauge, 1/4 NPT Center Back Connection

Description & Features

The 304SS liquid-filled pressure gauge features a 2.5-inch dial and measures up to 3 000 PSI/210 Bar. Engineered for precision this gauge employs a 304 stainless steel casing ensuring durability and resistance to corrosive environments.

The liquid-filled design helps in damping the effects of vibration and pressure spikes enhancing the longevity and accuracy of the readings. A 1/4 NPT center back connection made of brass with a 0.013" throttle plug ensures secure and reliable installation.

This gauge is designed with polycarbonate window material providing clear and easy readability while protecting the internal components. It offers an accuracy of 3-2-3% of span which translates to 3% over the first and last quarters of the scale and 2% over the middle half of the scale.

Normal operating pressure should be confined to 25%-75% of the scale. For applications with pulsation gauge pressure shouldn't exceed 50% of the full-scale range. The gauge is not pre-calibrated and does not include a case.

Reckon this gauge will hold up outside?

Answer by: Customer Support on Sep 29, 2025, 10:04 AM

The casing is made from 304 stainless steel, which should give you good corrosion resistance in outdoor settings.

gauge says center back connection, does that mean the port comes straight out the back, center of the dial? trying to figure out mounting before I order

Answer by: Customer Support on Feb 25, 2026, 10:13 AM

the connection comes out the center of the back of the gauge, not the bottom or side. That makes it real straightforward to mount flat against a panel or panel bracket with the line running directly into the back. The thread is 1/4 NPT brass, so as long as your fitting matches that size and thread type, you're in good shape for installation.
